Mix all of the marinade ingredients together in a blender. Marinate the fish — I used a boneless filet — for at least 12 hours and no more than 36 hours. I served it with Chinese broccoli (you could use broccoli rabe), stir-fried in tamari, ginger, and garlic. I also made a purée of parsnips and sunchokes, with a little bit of cream, and a tiny bit of salt and sugar. Serves 2
